Abstract
Description
Die Erfindung betrifft eine Rückenlehne für einen Fahrzeugsitz gemäß dem Oberbegriff von Anspruch 1.The The invention relates to a backrest for one Vehicle seat according to the preamble of claim 1.
Eine
derartige Rückenlehne
ist z.B. aus der
Der erste Lehnenteil weist eine sich unter den zweiten Lehnenteil erstreckende unteren Verlängerung auf, an der der zweite Lehnenteil angelenkt ist. Zwischen dem ersten und dem zweiten Lehnenteil ist eine Verriegelungseinrichtung vorgesehen, die z.B. durch ein an einem Lehnenteil vorgesehenes Drehfallenschloss und einen am anderen Lehnenteil vorgesehenen Verriegelungsbolzen gebildet sein kann. Das zweite Lehnenteil kann nach Entriegelung separat um eine erste Schwenkachse vorgeklappt werden und hierbei als Durchlade vom hinteren Laderaum her dienen oder eine Ablagemöglichkeit oder Armlehne für die Benutzer darstellen. Im verriegelten Zustand kann der zweite Lehnenteil zusammen mit dem ersten Lehnenteil als größerer Lehnenbereich um eine zweite Schwenkachse vorgeklappt werden, die vorteilhafterweise oberhalb der Klappachse des zweiten Lehneteils liegt.Of the first backrest part has a extending under the second backrest part lower extension on, on which the second backrest part is articulated. Between the first and the second backrest part a locking device is provided, the e.g. by a provided on a backrest part rotary latch lock and a locking bolt provided on the other backrest part can be formed. The second backrest part can be unlocked separately be folded forward about a first pivot axis and this as a through-loading serve from the rear cargo space ago or a storage facility or armrest for represent the users. In the locked state, the second Backrest part together with the first backrest part as a larger backrest area a second pivot axis are folded forward, which advantageously above the folding axis of the second Lehneteils lies.
Die
Die
Der Erfindung liegt die Aufgabe zugrunde, eine Rückenlehne zu schaffen, die ein vom Benutzer mit geringem Aufwand zu entriegelndes und nach Entriegelung wahlweise vorklappbares zweites Lehnenteil aufweist, das eine hohe Sicherheit, insbesondere auch eine Sicherheit bei einem Frontal-Crash, gewährleistet. Diese Aufgabe wird durch eine Rückenlehne nach Anspruch 1 gelöst. Die Unteransprüche beschreiben bevorzugte Weiterbildungen.Of the Invention has for its object to provide a backrest, the an unlocked by the user with little effort and after unlocking optionally pre-folding second backrest part, which has a high Safety, in particular a security in a frontal crash guaranteed. This task is accomplished by a backrest solved according to claim 1. The dependent claims describe preferred developments.
Erfindungsgemäß ist somit zwischen den beiden Lehnenteilen zusätzlich zu der seitlichen Verriegelungseinrichtung eine Crash-Verriegelungseinrichtung zwischen der unteren Verlängerung des ersten Lehnenteils und dem zweiten Lehnenteil vorgesehen, die bei einer langsamen Vorklappung des zweiten Lehnenteils nicht aktiviert und bei schnellem Vorklappen – wie es bei einem Frontal-Crash bei von hinten drückendem Gepäckstück auftritt – aktiviert ist.According to the invention is thus between the two backrest parts in addition to the lateral locking device a crash locking device between the lower extension provided the first backrest part and the second backrest part, the not activated at a slow Vorklappung the second backrest part and with fast folding - like it occurs in a frontal crash with baggage pushing from behind - activated.
Um die Aktivierung nur bei schnellem Vorklappen auszulösen, ist vorteilhafterweise am zweiten Lehnenteil ein Arretierungsmittel, z.B. eine nach hinten abstehende Klinke mit nach oben weisendem Haken, vorgesehen, das in der verriegelten Gebrauchslage des zweiten Lehnenteils angehoben und zumindest teilweise hinter einem Arretierungsteil der unteren Verlängerung des ersten Lehnenteils, z.B. einem Bügel, positioniert ist. Bei einer Vorklappbewegung des zweiten Lehnenteils fällt das Arretierungsmittel aufgrund seines Eigengewichtes nach unten. Bei langsamem Vorklappen ist sein Fallweg hinreichend groß, so dass es an dem Arretierungsteil vorbei gelangt; bei schnellem Vorklappen ist sein Fallweg hinreichend klein, so dass es das Arretierungsteil erfasst und einfängt.Around activation is only triggered by fast folding Advantageously, a locking means on the second backrest part, e.g. a rearwardly projecting pawl with upwardly pointing hook, provided in the locked position of use of the second backrest part lifted and at least partially behind a locking part of the lower extension of the first backrest part, e.g. a bracket, is positioned. at a Vorlappbewegung the second backrest part falls the locking means due to its own weight down. With slow folding his Fallweg is sufficiently large, so that it past the locking part arrives; with fast folding his fall path is sufficiently small, so that it captures and captures the locking part.
Zum Anheben des Arretierungsmittels kann vorteilhafterweise ein am zweiten Lehnenteil angelenkter Schwenkhebel dienen, der in der verriegelten Gebrauchslage des zweiten Lehnenteils an der unteren Verlängerung anliegt und hierdurch mit Kraft beaufschlagt ist. Die Anbindung des Schwenkhebels an der Klinke erfolgt vorteilhafterweise über eine Langloch-Bolzen-Führung, die bereits bei leichter Entlastung des Schwenkhebels ein hinreichendes Abfallen der Klinke ermöglicht.To the Lifting the locking means may advantageously be on the second Backrest pivot hinged lever serve, in the locked position of use of the second backrest part bears against the lower extension and thereby is acted upon with force. The connection of the swivel lever to the Latch advantageously takes place via a slot-bolt guide, the even with slight relief of the pivot lever a sufficient Fall of the latch allows.
